Summary: | PROBLEM TO BE SOLVED: To provide an adhesive composition capable of achieving an adhesive having suppressed reduction of transparency due to oil.SOLUTION: An adhesive composition for forming an adhesive containing a (meth)acrylic polymer contains (A) Calkyl (meth)acrylate, (B) an alicyclic monomer and (C) a monomer having at least one of a hydroxyl group or a carboxyl group as monomer components constituting the (meth)acrylic polymer. Average carbon number of the alkyl group in the component (A) is 8 or less. The monomer component contains the monomer (C) of 3 wt.% or more and a relationship of weight of the monomer (B) Wb and weight of the monomer (C) Wc satisfies 0.8≤Wb/Wc.SELECTED DRAWING: None
【課題】油による透明性の低下が抑制された粘着剤を実現できる粘着剤組成物を提供する。【解決手段】(メタ)アクリル系ポリマーを含む粘着剤を形成するための粘着剤組成物であって、該(メタ)アクリル系ポリマーを構成するモノマー成分として(A)C2−18アルキル(メタ)アクリレート、(B)脂環式モノマー、および(C)ヒドロキシ基およびカルボキシ基の少なくともいずれかを有するモノマー、を含む粘着剤組成物が提供される。上記(A)における上記アルキル基の平均炭素数は8以下である。上記モノマー成分は、上記(C)を3重量%以上含み、かつ上記(B)の重量Wbと上記(C)の重量Wcとの関係が0.8≦Wb/Wcを満たす。【選択図】なし |
